Rosera starts the period under partly cloudy, with the mercury at 32 °C and a feels-like of 39 °C. Today's forecast calls for thunderstorm, topping out near 36 °C before falling back to 27 °C overnight. Winds blow mainly from the E around 19 km/h, with gusts up to 39 km/h. Daytime highs hold fairly steady this week, staying within 36 to 37 °C. Rain is in the picture on Saturday, with roughly 4 mm expected in total across the week. Tomorrow brings thunderstorm with a high of 36 °C and a 33% chance of precipitation. The UV index reaches 8 today, so sun protection is sensible during the middle of the day. With the apparent temperature pushing into heat-stress territory, limit strenuous outdoor activity in the afternoon and stay hydrated. Sunrise comes at 04:55 and sunset at 18:39, giving 13.7 hours of daylight. Current humidity sits at 67% with pressure near 1000 hPa.

Soil temperatures today read surface 27.1 °C, 6 cm 30.8 °C, 18 cm 33.1 °C, 54 cm 30.9 °C. Soil moisture sits at 0-1 cm at 0.17 m³/m³, 3-9 cm at 0.17 m³/m³, 27-81 cm at 0.18 m³/m³. For wheat, the root-zone reading is below the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 39 mm against only 4 mm of expected rain — a 36 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 06:00 on 2026-06-21, with winds at or below 12 km/h and no rain expected. Heat stress is likely for wheat with highs reaching 37 °C (threshold 32 °C).
